Subject: [PATCH 3/3] rsi: fix static checker warning
Date: Tue, 11 Jul 2017 19:57:53 +0530 [thread overview]
Message-ID: <1499783273-15428-3-git-send-email-amitkarwar@gmail.com> (raw)
In-Reply-To: <1499783273-15428-1-git-send-email-amitkarwar@gmail.com>
From: Amitkumar Karwar <amit.karwar@redpinesignals.com>
u32 pointer is changed to u16 and filled the value. Problem is
solved by using local temporary variable. Below static checker
warning was reported.
drivers/net/wireless/rsi/rsi_91x_usb.c:400 rsi_usb_master_reg_read()
warn: passing casted pointer 'value' to 'rsi_usb_reg_read()'
32 vs 16.
Fixes: b97e9b94ad75c ("rsi: Add new host interface operations")
